I watched all your vids regarding this welder. Great to watch and made me laugh with your throw away comments. Most importantly very informative. Thank you for taking the time to post!

Just a tip if your interested ...Add a slight angle to your gun and push the puddle and the soot will mostly all disappear. Straight on always makes a lot of soot on the sides of the weld, drag angle will cover the whole weld with soot but push is clean and pretty. A little forward and back forward and back makes a weld similar to a tig look.

Impressive tool John - Doug on SV Seeker channel used a spool gun for all his pilot house - very fast method.

Thats a another great video John..

great vid John !

This is the kind of person I want to teach me.

Welded on 13amps, by a mechanic that pisses about LOL

That weldment seems to have suffered the worst it could ever expect to face and survived, and that's all I need to know!

once befor you had a concern about phosgene in brake cleaner the propellent was I think was a cfc an r-12 leak detector "sniffer" burns the cfc and produces phosgene its a phosgene detector I was a mechanic your always learning in that job yup the spool gun fast, nice result the 13 amps is the good part a rhombic drive helium solar stirling engine powerd plasma cutter cutting aluminum of any thickness wow I I pay 9-10 cents a kwh and it still stacks up sunny days id pay nothing

So, a little pre-heat might improve the weld too then, bearing in mind these are experimental test welds?

Hi John, i've just purchased the R-TECH I-180 mig welder based on your previous review, as i wanted a machine with decent capabilities for hobby auto/home fabrication. Looking at this segment John, the I-180 seems to weld better on higher power/metal thickness, i suppose this down to the higher amperage heating the aluminium quicker. My questions are, in what circumstances would you use ally mig, and when would you use tig instead, and would an higher gas pressure reduce the sooting effect or is this down to the metal actuallybeing burned in the welding process? I'm a newbie to all this mate so all info greatfully appreciated, and i really enjoy your videos so keep them coming. ;0)

Any chance you can do a outer corner weld for me to see how it goes if it can manage it well then i will buy one from R Tech ,can you use 1.5 or rather 2mm alloy coner weld as thats what i would be using it for thanks

did you change the U drive roller to suit 1.00 m.m or the factory one 0.6-0.8 m.m will work with 1.00 m.m ? thank you for help

john although u have finished these vedio pls can u tell me what aluminium wire u would need to weld 6061 grade aluminium thanks

great value for £160 John....

G'day John how would you suggest I go about learning to mig weld, I have never done welding before but it would be very handy to know how to do it in my work shop. I would appreciate your advice also on equipment needed for welding things like work benches ect, thank you regards John

What shield gas are you using? The soot (ie carbon) must come from somewhere! Is there CO2 in the mix?

Good to watch you pissing about the shop

Mechanic that pisses about describes many of us...The real test of a weld is when you load it heavy and then stand under it.
